What is Evolutionism

Evolutionism is a theory that states that life as we currently know it comes from a series of gradual changes in nature.

According to this current of thought, species undergo modifications that allow them to survive in nature, which is why it is usually associated as a synonym of Darwinism, which proposes something similar. However, Charles Darwin drew on evolutionism to create his famous theory on the origin of species.

Origin and development of evolutionism

Anaximander, a prominent Greek philosopher who lived between 610 and 545 BC, posed what is now considered one of the earliest antecedents of evolutionism. According to his hypothesis, the origin of life was in the water, where the first species were generated and from which man descended.

From the second half of the 19th century, evolutionism began to be considered a scientific theory, thanks to the French naturalist Jean-Baptiste Lamark (1744-1829), who stated that changes in environmental conditions generated modifications in living organisms. that allowed them to adapt and survive.

Evolutionism in Darwin

Finally, Charles Darwin (1809-1882) proposed his evolutionary theory based on “natural selection”: only organisms with the greatest capacity to adapt to the environment survive. This statement was made in his book The origin of specieswhich would become the essential scientific source for the development of evolutionary biology.
